12 Claims.

The present invention relates to a method and means for extracting superfluous hairs from the face, arms or other portion of the body, and to a novel mechanically actuated device for accomplishing the desired results.

Among the objects of the present invention is to provide a novel method for quickly and effectively removing superfluous hairs, and which is simple in the manner of operation and highly eifective in the results produced.

The present invention further comprehends a novel construction and arrangement in which any superfluous hairs are entrapped between two strips of adhesive tape on applying a requisite amount of gripping action and by a quick pull those hairs retained between the tapes are quickly and effectively removed.

A further object of the present invention is to provide a mechanism having a pair of rolls of adhesive or so-called Scotch extracted.

Further objects are to provide a construction of maximum simplicity, efflciency, economy and ease of assembly and operation, and such further objects, advantages and capabilities as will later more fully appear and are inherently possessed thereby.

The invention further resides in the construction, combination and arrangement of parts illustrated in the accompanying drawings, and while there is shown therein a preferred embodiment, it is to be understood that the same is susceptible of modification and change, and comfeatures and constructions without departing from the spirit of the invention.

In the drawings Figure 1 is a view in perspective of one embodiment of the novel device.

Fig. 2 is a view in front elevation thereof and showing the device applied to the face or other part of the body for removing superfluous hair.

Fig. 3 is a view in end elevation of the device.

Fig. 4 is an enlarged fragmentary View of the lower end of the device and showing the manner in which the hair is drawn by means of the strips of adhesive tape between a pair of springs or blades.

Fig. 5 is a view in front elevation of an alternate construction.

Fig. 6 is a similar view of another modification but requiring but one blade or leaf spring.

Referring more particularly to the embodiment selected to illustrate the invention in .Figs. 1 to 4, inclusive, the device there shown comprises a body, plate or support I having supported thereon a pair of rolls 2 of Scotch tape or other adhesive material. Each roll is freely rotatable upon a projection or supporting pin 3, and mounted intermediate and above these lOlls is a slotted pin 4 extending support or plate I and adapted to be manually rotated by a knurled knob 5 disposed at the rear of the support. This rotatably slotted pin 4 is adapted to receive the end of the combined or composite tape 6 from the two rolls 2, and by such rotation and Winding up of this combined tape tension is applied to the two strips of tape 7 as the latter are withdrawn from their respective rolls.

The tape from each of the rolls 2 is drawn over the lower end 8 of each of a pair of leaf springs or blades 9 and I B. These springs or blades are so constructed that the lower ends 8 are rounded, curved, bent or otherwise formed that when arranged in the manner shown these ends are held under compression. To accomplish this, the leaf spring 9 has its upper end disposed at one side of a, pin or projection H and its intermediate portion being disposed against the other side of a pin [2 over which the smooth side of adhesive tape 1 from one of the rolls passes.

To facilitate threading of the combined strip 5 between the springs or blades 9 and Ill and upon the rotatable pin 4, the end of this pin is slotted at E3 and the spring It is made readily adjustable and preferably removable. As more clearly shown in Figs. 1, 2 and 3, the spring I0 is disposed adjacent its lower end over one side of a pin or other projection 14, and has its upper extended end !5 disposed in a manner to be engaged by a rotatable crank arm It. This crank arm is mounted upon a rotatable pin or stub shaft 5? projecting through and to the rear of the body or support 5 to facilitate its manual operation, when required.

A pin [8 projects through and to the opposite sides of the crank arm intermediate its length, and the upper end of the leaf spring in is bifurcated or slotted at l9 to permit the free end of the crank arm to project therethrough. Thus as the stub shaft I! is rotated in a clockwise dithrough and journalled in the rection, the cross pins l8 bear against and depress the upper end of the spring or blade in and places it under tension, as shown in full lines in Fig. 2.

When the crank arm 16 is rotated in a counterclockwise direction as shown in dotted lines in Fig. 2, the tension on the spring or blade and its lower end 8 is relieved and it in turn relieves the tension on the tape I controlled by this blade or spring. I hus when the tension on this spring or blade is released, the spring may be removed or if maintained in position, the joined ends of the composite tapes may be readily fed between the ends 8 of the springs or blades, and the extreme end or juncture quickly secured in the slot I3 whereby rotation of the knurled knob 5 in a counter-clockwise direction withdraws the tapes from the supply rolls 2.

In the operation of the device, two rolls of adhesive tape are placed on the pins 3 and the ends thereof are withdrawn outside the pins [2 and I4. These ends are then joined together and threaded or directed between the ends 8 of the springs or blades 9 and HI, then disposed about the slotted pin 4 and the extreme composite end thereof anchored within the slot [3. In this feeding operation, the spring or blade [0 may have the tension thereof relieved by rotation of the stub shaft l1 and crank arm IS in a counter-clockwis direction, or it may be removed to further facilitate threading. After the end has been threaded into the slot [3 and the crank arm it moved to the full line position shown in Figs. 1 and 2, the ends 8 of the springs 9 and I0 apply the desired tension or pressure upon the composite tape where the separat tapes are joined and pass over and between the ends 8 upon rotation of the knurled knob 5.

When the assembled device is placed in contact with the face, arms or other part of the body from which unwanted or superfluous hairs are to be removed, the adhesive surface on the exposed face of the tapes engages and causes the hair or hairs adjacent thereto to adhere, and rotation of the knob 5 in a counter-clockwise direction withdraws the hairs with the tape into the space between the flat springs or blades 9 and II as shown in Fig. 4. In this position the hair or hairs are retained between the tapes and then as the operator pulls the device quickly in a manner similar to the operation of a pair of tweezers, those hairs are removed.

It is to be understood that the sticky or adhesive side of the tape 1 is on the outside until it passes over the rounded or curved ends 8, after which the adhesiv sides of the strips of tape are sealed to each other. After the operation has been completed, rotation of the knurled knob in a counter-clockwise direction exposes a new section of tape for removing additional h'airs, while that portion of the composite tape previously used is withdrawn to be rolled upon the pin 4. If desired, pins A may be employed for retaining the springs or blades in position.

In Fig. 5 is disclosed an alternate construction in which the spring or blade I9 is contoured at its lower end to provide an elongated surface 20 having its end rounded at 2|. In this construction, the tape 1 from one of the rolls 2 passes over this rounded end 2 I, then over the elongated surface 20, and then bends inwardly to pass between the adjacent surfaces on the springs or blades 9 and 19. In this form of the invention, the elongated surface 20 is moved into contact with the portion of the body from which a s, e

4 to be extracted, and causes the hairs to adhere to the tape over a relatively wide area.

Although we prefer to employ an adhesive tape such as Scotch tape, we have found that if such tape is not available, other tape, even one that may be devoid of adhesive, may be employed for the reason that the elongated surface 20 bends and directs the hairs toward the gripping edges formed where the adjacent surfaces on the springs or blades 9 and H) are disposed and where the tapes bend inwardly to form a composite strip. It is at this point that the tapes are compressed and direct the hairs into the space therebetween when the knob 5 is rotated in a counterclockwise direction and withdraws tape from the separate rolls. An adhesive tape is preferred for the reason that the sticky surface tends to facilitate directing the hairs to the pressure or compression point between the adjacent lower ends of the springs or blades.

In this alternate construction as in the device shown in Figs. 1 to 4, inclusive, a spring or blade i9 is placed under tension by means of a cam 22 mounted upon one end of a pin or rock shaft 23, with the other end of this pin or shaft preferably projecting beyond the cam so that it may be easily rotated to apply or relieve the tension on the spring or blade [9.

In Fig. 6 is disclosed a further alternate construction in which the support 24 has projecting therethrough a stub shaft 25 slotted at 26 for receiving the end of composite sheet 21 formed by joining the two strips of tape, one strip being supplied from the roll 28 mounted upon the pin 29 and the other strip by the roll 30 mounted upon the pin 3|. This roll 30 is of much larger diameter than the roll 28 and so mounted as to expose a considerable surface of the adhesive side of the tape to the hairs to be removed. In this form of the invention, only one spring or blade 32 is required, the spring or blade being mounted between spaced pins 33 or 34 in such manner as to apply tension to the spring and cause the lower end 35 thereof to be at all times pressed and maintained against the outer surface of the roll 30. Although we prefer employing a roll 28, good results may be had employing only the large adhesive roll 30 and drawing this tape over the end of the spring or blade 32.

In this embodiment and construction, the tape 36 from the roll 28 passes over the lower surface of the pin or projection 33 and over the lower or rounded end 35 of the spring or blade 32. As it passes over this rounded end 35, the lower or adhesive side of this tape is exposed and engages and combines with the adhesive side of the tape supplied from the larger roll 30, and causes the superfluous hairs to pass between the adhesive surfaces at this point, which provides a line contact between the separate tapes and forms the combined sheet or strip '21. Thus when the knurled knob 5 is rotated in a counter-clockwise direction, the hairs 31 adhering to the tape on the roll 35 will be drawn between the two strips of adhesive, withdrawn from rolls :28 and 35 and held by the compression force applied at this point by the spring or blade 32, and when these hairs have been securely anchored in this manner, a quick pull on the device will extract these hairs most effectively.

Although we have shown several illustrative embodiments of the novel invention, we do not wish to be limited to the particular details, features and assembly. For example, we show the ends of the blades or leaf springs bent or deformed to form the resilient surfaces for compair of tweezers is employed.

Having thus disclosed the invention, we claim.
